"EasyAdmin :: CrudUrlGenerator Symfony 6 无法正常工作"

Question

我正在使用 Symfony 6 和 EasyAdmin Bundle。 symfony 的仪表板是空的，没有数据可以显示，因为我使用仪表板来显示会议。

我写了以下代码

namespace App\Controller\Admin; 

use App\Entity\Comment; 
use App\Entity\Conference; 
use EasyCorp\Bundle\EasyAdminBundle\Config\Dashboard; 
use EasyCorp\Bundle\EasyAdminBundle\Config\MenuItem; 
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractDashboardController; 
use Symfony\Component\HttpFoundation\Response; 
use Symfony\Component\Routing\Annotation\Route;

class DashboardController extends AbstractDashboardController 
{
        #[Route('/admin', name: 'admin')]
        public function index(): Response
        {
            $routeBuilder = $this->get(CrudUrlGenerator::class)->build();
            $url = $routeBuilder->setController(MeetingCrudController::class)->generateUrl();
    
            return $this->redirect($url);
        }
}

但这给了我一个错误

1. 在 DashboardController 中找不到方法“获取”
2. 未定义的类'CrudUrlGenerator'

请问我该如何解决这些问题

您可以将 AdminUrlGenerator 注入构造函数并在 index 方法中使用它

private AdminUrlGenerator $adminUrlGenerator;

public function __construct(AdminUrlGenerator $adminUrlGenerator)
{
    $this->adminUrlGenerator = $adminUrlGenerator;
}

public function index()
{
    $url = $this->adminUrlGenerator
            ->setController(MeetingCrudController::class)
            ->generateUrl();

    return $this->redirect($url);
}
